I installed and set up routing-filter as described on the gem documentation page. https://github.com/svenfuchs/routing-filter

It works for the default locale. For example, if I set up my default locale as :en,the site is in English, and if I set my default locale as :zh, the site is in Chinese.

www.site.com/zh/home (the default locale path /en is automatically added to the URL)

But how can I make my site support BOTH languages?

when the default locale is :zh, I tried to change the URL by substituting the "zh" with "en" but the page is still in Chinese, not English.

Is this something not supported by the routing-filter gem? If not, is there some other gem I can use?

Or have I not set up the routing-filter gem properly?

Thanks!
